Cutting fluid application plays an important role in the improvement of cutting performance during machining processes. However, controlling the amount of the coolant used is important in terms of its effects on the environment, human health and also on the total cost of production. Another important concern is to avoid lowering the product quality and cutting tool life when the amount of coolant is decreased. The minimum quantity lubrication (MQL) method that has been developed in recent years is suitable for meeting these needs. In this study, the MQL technique was applied in the turning of AA7075 and AA2024 aluminium alloys. The samples were subjected to four different cutting speeds (150, 187.5, 240 and 300 m/min), two different feed rates (0.1 and 0.2 mm/rev) and four different flow rates (0.25, 0.45, 0.90 and 3.25 ml/min). At the end of experiments, it was observed that increased feed rate and cutting speed had a negative effect on surface quality, while increased flow rate exhibited a positive effect on surface quality.
